Incubation container

An incubation container, containing cultured cells, for observation through a microscope, comprising:

• a bottom and a sidewall;
• a partitioning member water-tightly partitioning an interior of said incubation container into a plurality of incubation chambers by perpendicular walls and water-tightly fitting to or formed integrally with a portion of the bottom of said incubation container, thereby capable of retaining in separation a liquid inputted in each of said incubation chambers from liquids in other incubation chambers;
• and
• a cover member covering an upper portion of each of said incubation chambers partitioned by said partitioning member and water-tightly fitted to or formed integrally with said partitioning member, the cover member having an under surface located at a level lower than the top of the sidewall and having an upper surface surrounded by a peripheral wall,
• wherein a whole or part of said cover member is formed of a transparent member, and
• the upper portion of each of said incubation chambers is partly formed with an opening that is not covered by the cover member, via which to input the liquid in each of said incubation chambers.
